[Laryngo-Tracheal Resection as an Alternative to Permanent Tracheostomy]

Cervical stenosis of the trachea caused by tracheotomy, tumor or without defined reason (idiopathic) can be treated by resection and anastomosis with good early and long-term results. Involvement of the ring cartilage makes the procedure technically demanding and increases the risk of morbidity. We describe our technique of laryngotracheal resection and reconstruction and compare the perioperative results with standard tracheal resection.

Between January 2005 and December 2015, we performed about 800 procedures on the trachea including 76 standard cervical tracheal resections and 35 laryngotracheal resection. Resections were carried out with direct anastomosis without intraoperative tracheotomy or intralaryngeal stenting. Patient records were retrospectively analysed for perioperative data.

The main cause of stenosis or defect of the trachea and operation was preceding tracheotomy. Idiopathic stenosis, tumors and subglottic stenosis in Wegener disease were less common. There were no disturbances of healing of the anastomosis in any patient. Tracheotomy in the course of treatment for intralaryngeal swelling or recurrent nerve palsy was necessary in 3 (standard) and 2 (laryngotracheal) patients. Postoperative tracheostomy was closed in all patients within 3 months. Pulmonary complications and recurrent nerve palsy occurred in 5/4 and 2/2 of the patients without significant differences between the 2 groups. One patient died in each group from pulmonary complications.

The laryngotracheal resection is a relevant part of cervical tracheal surgery. It can be performed without significantly higher morbidity and can restore lung function and quality of voice.
